The difference is the APR is stable because it's a stable coin not a variable APR like the stock market.
By the time anything happens in the US it will be at least a year if not longer. Congress will likely step in as there are some very big crypto components there that do not want to see any innovation hampered and see it as a massive opportunity for a huge win over China
An APR of 10% can’t currently be achieved without risk. It would be a disaster if this was possible.
Assets broadly get priced by:
Er = RF + B (Rm - Rf)
what this means in English is that assets need to beat the risk free rate. The risk free rate is what you’re describing above with stable coins - interest payments essentially without volatility.
If this is possible, this means that 95% of businesses can’t match this ROE or ROCE, as why would you invest in businesses that carry risk if you can make 10% interest in crypto.
To get to that 10% rate there must be significant risk. If there isn’t, if it’s genuinely risk free 10%(which is only really possible from a government with an army who can issue bonds and taxes) then the entire system of commerce grinds to a halt.
So, the crypto advocates will say, yes! Stocks and bonds are dead. Crypto is the way. Ok, so stocks are essentially discounted income streams to present value -ie they make and produce value over and above the purchase price. So what is this world that replaces it?
Tokens. Tokens of nominal value.
Blockchain will take over the administration of assets in the same way SETSQ and CREST took over settlement of trades, but the idea that this digital system of tokens could replace real assets just isn’t possible. It’s more the case that centralised administration will become decentralised.
